Cookie Transponders do need to meet TSO requirements as per 91.215: (a) All airspace: U.S.-registered civil aircraft. For operations not conducted under part 121 or 135 of this chapter, ATC transponder equipment installed must meet the performance and environmental requirements of any class of TSO-C74b (Mode A) or any class of TSO- C74c (Mode A with altitude reporting capability) as appropriate, or the appropriate class of TSO-C112 (Mode S). Interesting. *Up until recently the TRIG transponder was not TSO. They were offered for sale in the USA through various dealers. *So where did they get installed if they can't be used in US registered civil aircraft? I'll have to ask my boss again, but I believe the first TRIG we installed was not TSO. Cookie The issue is just the "must meet the performance...." part. That does not say must be a TSO approved part. It says it must meet the performance requirement of a TSO. My interpretation of this is if the A&P/IA signing off can determine though other specifications/tests etc. that the device meets those TSO requirements and they are comfortable signing off on the install then you have yourself a valid install. Of course those people do so at risk to their certificate, so not taken lightly. Again find yourself an A&P/IA you trust and follow their advice. Darryl- Hide quoted text - - Show quoted text - Yes, that is also how I interpret the FAR.........it's a "performance spec." But I don't think it is up to the IA (only) to decide if the device meets the spec. *This is why my boss provides "aproved data" to the FAA and they issue a "field approval". * The approved data could be as simple as the install manual. *This manual would contain the mfr's info which would show that the device performs to the FAR required TSO . My boss has a long standing relationship with the FAA. *These paperwork issues pose no problem. *We usually have the paperwork returned to us in 24 hours! *(I've heard of guys doing "do it yourself jobs" geting caught up in months of paperwork. One reason to pay the extra $$ an hire a pro) It's all paperwork......that way everyone involved has their butt covered. Bottom line, non TSO equipment CAN be installed, even transponders........... Cookie I disagree about the transponder. *I'd be interested in seeing a single Avionics Shop that would certify a non-TSOd transponder as meeting all the specifications of the applicable TSO and certifying their installation of that transponder as complying with 91.215. *This is not to say that some individual A&P or small shop might not pencil whip the paperwork and install it. *Again, this applies to transponders, not comm radios, as the regs for Part 91 ops do not require comm radios to meet a TSO. *You need *to review what "approved data" is. *It is not any manufacturer's specifications that you send in to the FAA and call it approved. *When you apply for a field approval you are submitting data (unapproved) that the FAA looks at and either approves for that single installation or disapproves.- Hide quoted text - - Show quoted text - Ok so you disagree. BUT...... It is not the avionics shop which "certifies" the (non tso) transponder, it is the FAA. That is why we get a field approval. The shop does not decide what is "approved data" the FAA decides that. We provide the data, the FAA evaluates it. We are not talking about "pencil wipping" anything here. Bottom line, a non- TSO transponder CAN be legally installed in a glider, if you do the paperwork, (and the transponder can be shown to comply with the TSO "standard".) This is all a moot point now since TRIG is now TSO............. Cookie |
